The pendant attachment device includes a fixing block, an attachment element rotatably and movably fixed in the compartment, a fixing plate fixed to the housing and an elastic element. The fixing block defines a compartment. The attachment element includes a main body defining a fixing hole, the string is threaded through the fixing hole. In a first state, the elastic element exerts an elastic force on the attachment element, causing the attachment element being latched with the latching block with the fixing hole is located in the opening. In a second state, the elastic element drives the attachment element to move away from the fixing plate, thereby making the fixing hole stick out of the opening. ## Claims ### Claim 1 A portable electronic device, comprising: a housing defining an opening; and a pendant attachment device comprising: a fixing block fixed to the housing, the fixing block defining a compartment communicating with the opening; an attachment element rotatably and movably fixed in the compartment, the attachment element including a main body defining a fixing hole for a string of a pendant to pass through, the fixing hole being located in the opening; a fixing plate fixed to the housing and aligned with the compartment; an elastic element fixed between the fixing plate and the attachment element; wherein the elastic element exerts an elastic force on the attachment element to drive the attachment element to move away from the fixing plate, thereby making the fixing hole be exposed out of the opening. ### Claim 2 (depends on 1) The portable electronic device as claimed in claim 1, wherein the fixing block including two limiting posts, the attachment element further includes two latching members protruding from the main body; each latching member defines a latching groove, each limiting post is latched in one of the latching grooves causing the attachment element being latched with the latching block in the first state. ### Claim 3 (depends on 2) The portable electronic device as claimed in claim 2, wherein the main body includes a first end; a slot is defined in the first end, facilitating rotating the attachment element. ### Claim 4 (depends on 3) The portable electronic device as claimed in claim 3, wherein the main body further includes a second end opposite to the first end; the latching members protrude from the second end. ### Claim 5 (depends on 4) The portable electronic device as claimed in claim 4, wherein a hook protrudes from a distal end of each latching member, each hook defines one of the latching grooves opposite to the other hook. ### Claim 6 (depends on 4) The portable electronic device as claimed in claim 4, wherein a first retaining post protrudes from the second end between the latching members, a second retaining post protrudes from a surface of the fixing plate facing the fixing element; one end of the elastic element is fixed to the first retaining post, the other end of the elastic element is fixed to the second retaining post. ### Claim 7 (depends on 4) The portable electronic device as claimed in claim 4, wherein the housing includes a main board and a sidewall protruding from an edge of the main body, the fixing block is fixed to the main board. ### Claim 8 (depends on 7) The portable electronic device as claimed in claim 7, wherein the fixing block includes a latching end opposite to the sidewall, two cutouts are defined in the latching end and located at two sides of the compartment; in the second state, the elastic element drives the attachment element to move into the cutouts, thereby making the fixing hole out of the opening. ### Claim 9 (depends on 8) The portable electronic device as claimed in claim 8, wherein the limiting posts protrude from the latching end and located another two sides of the compartment. ### Claim 10 A portable electronic device, comprising: a housing defining an opening; and a pendant attachment device comprising: a fixing block fixed to the housing, the fixing block defining a compartment communicating with the opening; an attachment element rotatably and movably fixed in the compartment, the attachment element including a main body defining a fixing hole for a string of a pendant passing through; a fixing plate fixed to the housing and aligned with the compartment; an elastic element fixed between the fixing plate and the attachment element; wherein the attachment element is latched with the fixing block to make the fixing hole is located in the opening; after the attachment element is released from the latching block, the attachment element is capable of rotating relative to the latching block, and the elastic element drives the attachment element to move away from the fixing plate, thereby making the fixing hole be exposed out of the opening. ### Claim 11 (depends on 10) The portable electronic device as claimed in claim 10, wherein the fixing block including two limiting posts, the attachment element further includes two latching members protruding from the main body; each latching member defines a latching groove, each limiting post is latched in one of the latching grooves causing the attachment element being latched with the latching block in the first state. ### Claim 12 (depends on 11) The portable electronic device as claimed in claim 11, wherein the main body includes a first end; a slot is defined in the first end, facilitating rotating the attachment element. ### Claim 13 (depends on 11) The portable electronic device as claimed in claim 11, wherein the main body further a second end opposite to the first end; the latching members protrude from the second end. ### Claim 14 (depends on 13) The portable electronic device as claimed in claim 13, wherein a first retaining post protrudes from the second end between the latching members, a second retaining post protrudes from a surface of the fixing plate facing the fixing element; one end of the elastic element is fixed to the first retaining post, the other end of the elastic element is fixed to the second retaining post. ### Claim 15 (depends on 13) The portable electronic device as claimed in claim 13, wherein a hook protrudes from a distal end of each latching member, each hook defines one of the latching grooves opposite to the other hook. ### Claim 16 (depends on 15) The portable electronic device as claimed in claim 15, wherein the housing includes a main board and a sidewall protruding from an edge of the main body, the fixing block is fixed to the main board. ### Claim 17 (depends on 16) The portable electronic device as claimed in claim 16, wherein the fixing block includes a latching end opposite to the sidewall, two cutouts are defined in the latching end and located at two sides of the compartment; the attachment element rotates relative to the latching block till after the hooks are aligned with the cutouts, the elastic element drives the attachment element to move into the cutouts, thereby making the fixing hole be exposed out of the opening. ### Claim 18 (depends on 17) The portable electronic device as claimed in claim 17, wherein the limiting posts protrude from the latching end and located another two sides of the compartment.
