The utility model provides an auxiliary clamp 100, this auxiliary clamp 100 is used for nailing.

Referring to fig. 1, in an embodiment of the present application, an auxiliary clamp 100 includes two clamp arms 10 and a clamp head 30, the two clamp arms 10 are hinged to each other, the two clamp arms 10 can move toward or away from each other under external force, the clamp head 30 includes a first clamp block 31 and a second clamp block 33, the first clamp block 31 and the second clamp block 33 are respectively connected to one clamp arm 10, the first clamp block 31 and the second clamp block 33 can move toward or away from each other under the driving of the clamp arms 10, and can enclose a fixed space 30b and a limiting space 30a that are communicated with each other when moving toward each other, and the fixed space 30b and the limiting space 30a are stacked in a direction where a hinge center axis of the two clamp arms 10 is located.

The direction of the central axis of the two forceps arms 10 is perpendicular to the ground when the auxiliary forceps 100 is laid on the ground, and the position a in fig. 1 is the center of the hinge.

The binding clip 30 may be made of a metal material such as steel, iron, etc. to prevent deformation when the hammer is struck. The clamp arm 10 may be made of metal material such as steel or iron, and the clamp arm 10 may be made of plastic in order to ensure the hand feeling of holding. In order to improve the hand feeling of holding, the holding portion of the caliper arm 10 may be further curved to facilitate the holding force.

The utility model discloses technical scheme provides an auxiliary clamp 100 includes tong arm 10, first clamp splice 31 and second clamp splice 33, can form the spacing space 30a and the fixed space 30b that are linked together when first clamp splice 31 and second clamp splice 33 move in opposite directions, and fixed space 30b and spacing space 30a along the range upon range of setting of the articulated center pin place direction of two tong arms 10. In use, a nail can be fixed in the fixing space 30b, and the auxiliary clamp 100 is held to a position to be worked and struck with a hammer. When the hammer is used, the hammer head can be at least partially swung into the limiting space 30a, and a nail fixed in the fixing space 30b is knocked to drive the nail into a position to be worked. So, can avoid the hammer to pound the hand when nailing. In addition, because the nail is held in the fixing space 30b for limiting, the nail is not easy to shake when being knocked, thereby preventing the nail from being askew due to the fact that the hammer is swung askew, and ensuring the stability of the nail after being driven.

Referring to fig. 1, in an embodiment of the present application, the limiting space 30a and the fixing space 30b are cylindrical spaces, and the limiting space 30a overlaps with a central axis of the fixing space 30 b. Because the nail is fixed in the dead space 30b by spacing, when the hammer is beating the nail, its tup is also spacing in dead space 30a, consequently, overlap the central axis setting with dead space 30a and dead space 30b and can make the hammer when beating, the central line of its tup can overlap with the central line of nail to make the nail atress more even when being beaten, difficult quilt nail is askew or warp, can guarantee that the nail is difficult for dropping after the nail is gone into and treats the operation position.

To further ensure that the nail is not skewed, the surface of the auxiliary clamp 100 that contacts the work site when driving the nail may be flat.

Referring to fig. 1, in an example embodiment of the present application, each of the first clamping block 31 and the second clamping block 33 includes a main block 311 and a sub-block 313, the main block 311 is connected to the caliper arm 10, the main blocks 311 of the first clamping block 31 and the second clamping block 33 can move toward or away from each other under the driving of the caliper arm 10 and can enclose a limiting space 30a when moving toward each other, the sub-blocks 313 are stacked on the surface of the main block 311, and the sub-blocks 313 of the first clamping block 31 and the second clamping block 33 can move toward or away from each other under the driving of the main block 311 and can enclose a fixing space 30b when moving toward each other.

In an exemplary embodiment of the present application, the sub-block 313 is detachably connected to the main block 311, so that it is possible to easily replace the sub-block 313 of different types, thereby changing the size of the fixing space 30b to accommodate nails of different types.

In one embodiment of the present application, the main block 311 is detachably connected to the jawarm 10. Therefore, after the long-term wear and tear caused by use, only the part of the clamp head 30 is replaced, and the cost is saved. When the main block 311 and the sub block 313 are of an integral structure, replacing the main block 311 can also replace the sub block 313 at the same time to fit different types of nails.

In an example embodiment of the present application, the facing sides of the main blocks 311 of the first clamping block 31 and the second clamping block 33 are recessed towards opposite directions to form two limiting grooves 31a, the limiting space 30a is formed by the two limiting grooves 31a when the first clamping block 31 and the second clamping block 33 move towards each other, the facing sides of the sub blocks 313 of the first clamping block 31 and the second clamping block 33 are recessed towards opposite directions to form two fixing grooves 31b, and the fixing space 30b is formed by the two fixing grooves 31b when the first clamping block 31 and the second clamping block 33 move towards each other.

The provision of the fixing groove 31b increases the contact area of the nail with the sub-block 313, so that the nail is more firmly held and fixed in the stopper space 30a, preventing the nail from being displaced when the hammer is struck. The limiting groove 31a is arranged to further limit the position of the hammer head in the limiting space 30a, so that the nail is stressed more uniformly when the hammer strikes the nail.

In an example embodiment of the present application, a surface of the sub-block 313 facing away from the fixing groove 31b is connected to a groove wall of the stopper groove 31 a.

The surface of the sub-block 313 facing away from the fixing groove 31b may be partially connected to a groove wall of the stopper groove 31 a. The surface of the sub-block 313 facing away from the fixing groove 31b may be entirely connected to the groove wall of the stopper groove 31a for enhancing the connection strength. By connecting the auxiliary block 313 and the main block 311 in this way, the volume of the auxiliary block 313 can be reduced, so that the manufacturing cost is saved, the weight of the auxiliary clamp 100 is reduced, and the auxiliary clamp is convenient to take.

Of course, the sub-block 313 may be connected to the surface of the main block 311 facing the position to be worked, and will not be described in detail herein.

Referring to fig. 1, in the present embodiment, the fixing groove 31b may be an arc-shaped groove in order to match with the round nail. It will be appreciated that the fixing grooves 31b may be square grooves or other irregular grooves in order to accommodate nails of different shapes.

Referring to fig. 1, in the present embodiment, the limiting groove 31a is an arc-shaped groove. It is understood that the fixing groove 31b may be a square groove or other irregular-shaped groove in order to match differently shaped hammers.

Referring to fig. 1, in order to facilitate the passing of the handle of the hammer and prevent the handle of the hammer from influencing the driving of the nail, a yielding groove 31c is further formed in one side of the main block 311, which is away from the auxiliary block 313, and the yielding groove 31c penetrates through the main block 311 and is communicated with the limiting space 30 a.

The avoiding groove 31c has a groove bottom wall and a groove side wall connected to the groove bottom wall, and in this embodiment, in order to further prevent the handle of the hammer from affecting the hammer to strike the nail, the groove bottom wall of the avoiding groove 31c may be flush with the side of the sub-block 313 facing the limiting space 30 a.
