## Abstract

A hand puller with a detachable handle includes a body, an axle, and a handle. The axle is passed and mounted onto the body, and a sheath opening is formed at an end of the handle for sheathing an edge of the axle, such that the handle can be turned by using the axle as an axial center, and a guide section is defined and formed at an external periphery of the sheath opening, and the body includes at least one stop portion protruded from a position proximate to the guide section of the handle. When the handle is turned by using the axle as the axial center, the guide section and the stop portion are slidably coupled to restrict a radial movement of the handle to prevent the handle from being separated from the axle along the radial direction.

## Claims

### Claim 1

A hand puller with a detachable handle comprising:
a body with a first side plate and a second side plate, each side plate having a penetrating hole;
an axle installed on the body and extending through a penetrating hole on each side plate, the axle having two ends;
a first ratchet wheel and a second ratchet wheel, the first ratchet wheel being mounted on the axle adjacent to the first side plate and the second ratchet wheel being mounted on the axel adjacent to the second side plate; and
a handle with a sheath opening for sheathing onto both end of the axle, the handle defining and forming a guide section at an external periphery of the sheathing opening,
wherein
the body includes a first brake plate embedded and latched to two ratchet wheels for limiting two ratchet wheels and the axle to rotate toward a first direction only, the body also includes a stop portion protruded from a position proximate to the guide section of the handle,
the handle includes a second brake plate embedded and latched to two ratchet wheels, such that the handle can push two ratchet wheels in one direction and synchronously drive the axle to coil a rope,
when the handle is turned in a direction opposite of the first direction by using the axle as an axial center,
the guide section of the handle and the stop portion of the body are slidably coupled with each other, and a radial movement of the handle is limited to prevent the handle from being separated from the axle in a radial direction.

### Claim 2 (depends on 1)

The hand puller with a detachable handle of claim 1, wherein the body further includes an upper latch portion and an indentation formed sequentially on the first side plate and on the second side plate, and two stop portions are disposed on front ends of the two side plates, and the body also includes a brake base disposed at a rear end of the first side plate and the second side plate for accommodating the first brake plate, and a compression spring installed between the brake base and the first brake plate, such that the first brake plate exerts a propping force towards the penetrating hole of the body.

### Claim 3 (depends on 2)

The hand puller with a detachable handle of claim 2, wherein the body includes a rope rod passed into a rear end of the body.

### Claim 4 (depends on 2)

The hand puller with a detachable handle of claim 2, further comprising a bump disposed at an external periphery of each side plate, such that if the handle is turned to a position of the bump of the body, the guide section of the handle will not be stopped by the stop portion of the body and can be upwardly detached from the axle.

### Claim 5 (depends on 1)

The hand puller with a detachable handle of claim 1, wherein the handle includes a slide slot formed symmetrically and separately on both sides of the handle and provided for accommodating the second brake plate, and the second brake plate is abutted by a torque spring to provide a propping force in a direction towards the sheath opening of the handle, such that the second brake plate can be embedded and latched to the corresponding ratchet wheel along the slide slot, and the handle can be used for pushing the corresponding ratchet wheel in a one-way direction to synchronously drive the axle to coil a rope when the handle is turned in an opposite rotational direction of the first brake plate by using the axle as an axial center.

### Claim 6 (depends on 1)

The hand puller with a detachable handle of claim 1, wherein the guide section of the handle is substantially in a circular arc shape.
