## Abstract

A trigger device is configured to trigger a Hall sensor located above the trigger device and the trigger device includes a body, a pressing member and a pushing member. The body includes a base, an elastic member and a shaft. The elastic member is disposed in the base and the shaft is pivotally connected to the base. The pressing member is pivotally connected to one end of the shaft. The pushing member is pivotally connected to the other end of the shaft, slidably disposed on the base and holds against the elastic member. When the pressing member is pressed, the pressing member pushes the shaft to rotate and push the pushing member to undergo a displacement so that a position of a magnetic member of the pushing member and a position of the Hall sensor overlap. And the pushing member squeezes the elastic member to generate an elastic restoring force.

## Claims

### Claim 1

A trigger device configured to trigger a Hall sensor located above the trigger device, the trigger device comprising:
a body comprising a base, an elastic member, and a shaft, the elastic member being disposed in the base, and the shaft being pivotally connected to the base;
a pressing member pivotally connected to one end of the shaft; and
a pushing member comprising a magnetic member, the pushing member being pivotally connected to the other end of the shaft and slidably disposed on the base, and the pushing member holding against the elastic member, when the pressing member is pressed, the pressing member pushing the shaft to rotate and push the pushing member to create a displacement, so that a position of the magnetic member and a position of the Hall sensor overlap, and the pushing member compressing the elastic member to generate an elastic restoring force.

### Claim 2 (depends on 1)

The trigger device according to claim 1, wherein the base comprises a positioning column, and the pushing member comprises an holding portion, the elastic member being sleeved on the positioning column and holding against the base at one end, and the holding portion of the pushing member passing through the positioning column and correspondingly holding against the other end of the elastic member.

### Claim 3 (depends on 2)

The trigger device according to claim 2, wherein the shaft comprises a receiving slot, the shaft rotates so that the positioning column passes through the receiving slot after the pressing member is pressed.

### Claim 4 (depends on 2)

The trigger device according to claim 2, wherein the base further comprises two assembly plates disposed on two sides of the positioning column and parallel to each other, and the shaft comprises two rotation shafts protruding toward left and right sides respectively, each of the rotation shafts being pivotally disposed on one of the assembly plates, and the shaft being disposed between the two assembly plates.

### Claim 5 (depends on 1)

The trigger device according to claim 1, wherein the base further comprises two assembly plates parallel to each other, and the shaft comprises two rotation shafts protruding toward left and right sides respectively, each of the rotation shafts being pivotally disposed on one of the assembly plates, and the shaft being disposed between the two assembly plates.

### Claim 6 (depends on 1)

The trigger device according to claim 1, wherein the base comprises a pivoting slot and an opening, and the pressing member comprises a pivotal shaft, the pivotal shaft being assembled into the pivoting slot through the opening and being pivoted in the pivoting slot.

### Claim 7 (depends on 1)

The trigger device according to claim 1, wherein a first groove and a second groove are respectively disposed on two ends of the shaft, the pressing member being pivotally connected to the first groove, and the pushing member being pivotally connected to the second groove.

### Claim 8 (depends on 7)

The trigger device according to claim 7, wherein the magnetic member is disposed at one end of the pushing member, and the other end of the pushing member has a crossbar pivotally disposed in the second groove.

### Claim 9 (depends on 8)

The trigger device according to claim 8, wherein the base comprises two limiting slots, and the pushing member further comprises two limiting members, the two limiting members passing through and sliding in the two limiting slots, and when the shaft is rotated, the second groove pushing the crossbar pivotally disposed therein, to push against the pushing member, so that the pushing member is moved along the limiting slots through the limiting members to create the displacement.

### Claim 10 (depends on 1)

A handheld pistol grip assembled to an electronic device having a Hall sensor, the handheld pistol grip comprising:
a pistol grip body comprising a fixing portion and a handle, the handle extending downward from the fixing portion, and the electronic device being assembled to the fixing portion; and
the trigger device according to claim 1, the trigger device being assembled to the handle and located below the Hall sensor, and the magnetic member being adjacent to the electronic device.
