SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pin extracting tool to solve and to provide in the above-mentioned background art because of a word screwdriver when dismantling the pin, there is the lifting surface area little, do not have the strong point scheduling problem, make the pin dismantle inefficiency on the one hand, on the other hand has increased the problem of the cost of labor when overhauing.

In order to achieve the above object, the utility model provides a following technical scheme: pin extracting tool, including the sled head, the main part of sled head is the rectangular block, the front side of rectangular block is provided with the cushion, the surface of rectangular block is provided with the wedge, the intermediate position of wedge is provided with the recess, the internal surface of wedge is provided with the sawtooth, the right-hand member of sled head is provided with the pinch bar.

Preferably, the periphery of the rectangular block is provided with a round angle.

Preferably, the cross section of the cushion block is trapezoidal.

Preferably, the inner surface of the wedge-shaped block is wave-shaped and vertical to the upper surface of the rectangular block, a wedge angle is formed between the outer surface of the wedge-shaped block and the upper surface of the rectangular block, and round corners are arranged on the periphery of the wedge-shaped block and the edge connected with the rectangular block.

Preferably, the groove is provided with an inclined opening, and the opening of the groove is large outside and small inside.

Preferably, the pry head is made of chrome-molybdenum alloy steel, and the pry bar is made of low-carbon alloy steel.

Preferably, the pry head and the pry bar are fixedly connected in a welding mode.

Compared with the prior art, the beneficial effects of the utility model are that:

the front side of rectangular block sets up the cushion, as supporting when conveniently prying the pin, and the middle part of wedge sets up the bevel connection recess, conveniently knocks in the sieve clearance, catches on the pin pole, colludes the pin tightly so that pry out smoothly to reduce the time of dismantling the pin, thereby improve the sieve and change efficiency in order to reduce the cost of labor.

In the figure: 1 crow head, 2 crowbars, 3 rectangular blocks, 4 cushion blocks, 5 wedge-shaped blocks and 6 grooves.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Example (b):

referring to fig. 1-3, the present invention provides a technical solution: pin extracting tool, including sled head 1, the main part of sled head 1 is rectangular block 3, and the front side of rectangular block 3 is provided with cushion 4, and the surface of rectangular block 3 is provided with wedge 5, and the intermediate position of wedge 5 is provided with recess 6, and the internal surface of wedge 5 is provided with the sawtooth, and the right-hand member of sled head 1 is provided with pinch bar 2.

The periphery of the rectangular block 3 is set into a round angle, so that hands are prevented from being scratched when the hand-washing machine is used.

The cross section of the cushion block 4 is trapezoidal, so that support is formed above the sieve plate conveniently, and the problem that no supporting point exists when the pin is prized is avoided.

The internal surface of wedge 5 sets up to the wave, perpendicular with the upper surface of rectangular block 3, and the surface of wedge 5 becomes the wedge angle with the upper surface of rectangular block 3, and the edge that the periphery of wedge 5 and be connected with rectangular block 3 are provided with the fillet, are favorable to imbedding in the erection gap of sieve, guarantee the structural strength that wedge 5 and rectangular block 3 are connected, guarantee pin extracting tool's performance, avoid failing to prize out the phenomenon of pin because of the structure bending failure.
