Technical Field

The utility model relates to an automobile disassembling tool technical field especially relates to a relay pincers for auto repair.

Background

In the process of automobile maintenance, because the automobile is provided with a plurality of relays, the relays are generally pulled out by hands during disassembly, so that the relays are easy to slide by hands and difficult to pull out; the conventional vice or nipper pliers are used for pulling, so that the relay shell is easily damaged.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned problem among the prior art, the utility model provides a relay pincers for auto repair has solved current auto repair in-process relay and has extracted the problem that is unsmooth and harm the relay shell easily.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:

the utility model provides a relay pincers are used in auto repair, its includes the tong arm of two cross pivot connections, and the pivot is connected respectively on two relative shear plates to the one end of two tong arms, and the other end of two tong arms forms handle portion. The opposite sides of the two shearing plates are provided with cutting edges, the upper ends of the two shearing plates are respectively fixed with oppositely arranged relay nippers, and the handle part is connected to the lower ends of the shearing plates in a sliding manner through a connecting pin. The relay nipper includes the first riser with clipboard fixed connection, and the top integrated into one piece of first riser has the diaphragm of keeping away from another relay nipper one end extension, and the end fixing of diaphragm has the second riser, is fixed with the fine hair pad on the medial surface of first riser and the top surface of diaphragm.

Furthermore, the first vertical plate of the relay clamp plate is sleeved on the top end of the shear plate and is locked and fixed through a threaded fastener.

Further, the first vertical plate is matched with the shear plate in a wedge shape, and the end face of the first vertical plate is flush. The wedge-shaped surfaces matched with the wedge-shaped surfaces can increase the contact area of the relay nipper and the shear plate, and improve the transmission efficiency of the acting force applied to the handle part.

Furthermore, the bottom of the shear plate is provided with a rectangular groove along the vertical direction, and a connecting pin fixed on the handle part is inserted in the rectangular groove and vertically slides in the rectangular groove. The shearing parts and the relay nipper which are oppositely arranged are guaranteed to vertically move and move in parallel all the time, so that the force applied by the relay nipper to the relay shell is more uniform, and the relay is not easily damaged.

Further, the length of the handle portion is no less than 5/6 of the length of the jawarm. The clamp arm becomes a labor-saving lever, and a user can pull the relay down by applying a small force.

Further, the two handle portions are arc-shaped rods bent in opposite directions. For easy handling by the user.

The utility model has the advantages that: rectangular cavities formed by the second vertical plates and the transverse plates on the two oppositely arranged relay nipper plates can be matched with the appearance of the relay, so that the acting point range of the nipper plates and the relay is wider when the relay is pulled out; meanwhile, the friction force between the nipper and the relay shell can be increased by the fluff cushion, so that a user can easily pull out the relay through the relay nipper; meanwhile, the fluff pad has a buffering effect, and the relay shell can be prevented from being damaged by the nipper.

Be provided with the sword limit on the relative shear plate that sets up, can cut the fuse through the sword limit, extended the application range of this relay pincers, improved the commonality.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes will be apparent to those skilled in the art as long as they are within the spirit and scope of the present invention as defined and defined by the appended claims, and all inventions contemplated by the present invention are protected.

As shown in fig. 1, the relay clamp for automobile maintenance includes two clamp arms 1 which are cross-pivoted, one ends of the two clamp arms 1 are respectively pivoted on two oppositely arranged shear plates 2, and the other ends of the two clamp arms 1 form handle parts 11. The opposite sides of the two shear plates 2 are provided with blade edges 21, the upper ends of the two shear plates 2 are respectively fixed with oppositely arranged relay nipper plates 3, and the handle part 11 is connected to the lower ends of the shear plates 2 in a sliding manner through a connecting pin 111.

The relay clamp plate 3 comprises a first vertical plate 31 fixedly connected with the shear plate 2, a transverse plate 32 extending away from one end of the other relay clamp plate 3 is integrally formed at the top end of the first vertical plate 31, a second vertical plate 33 is fixed at the end part of the transverse plate 32, and a fluff pad 4 is fixed on the inner side surface of the first vertical plate 31 and the top surface of the transverse plate 32.

The first vertical plate 31 of the relay nipper 3 is sleeved on the top end of the shear plate 2 and is locked and fixed by a threaded fastener 34. Preferably, the first riser 31 is wedge-fitted with the shear plate 2 and flush in end face.

The bottom of the shear plate 2 is provided with a rectangular groove 22 in the vertical direction, and a connecting pin 111 fixed to the handle portion 11 is inserted into the rectangular groove 22 and vertically slides in the rectangular groove 22.

The length of the handle portion 11 is no less than 5/6 of the length of the jawarm 1. The pivot connection position of the two clamp arms 1 is a fulcrum of the lever, the handle part 11 is a driving arm of the lever, the length of the handle part 11 is not less than 5/6 of the length of the clamp arm 1, namely the length of the driving arm of the lever is more than 5 times of the length of the driving arm, a user only needs to apply 1/5 of force required by pulling out the relay to pull out the relay, and difficulty and working strength of pulling out the relay can be reduced. The two handle portions 11 are arc-shaped bars bent in opposite directions to facilitate gripping by a user's one or both hands.

During the use, the medial surface of second riser 33 and the top surface of diaphragm 32 respectively with two mutually perpendicular's face contacts on the relay, owing to there is the effect of fine hair pad 4, make relay nipper 3 be difficult to with the relay shell slippage. Make two relative second risers 33 also to the outside removal through rotating handle portion 11 to the outside, connecting pin 111 upwards slides for shear plate 2, the increase of interval space between two second risers 33, can make things convenient for the relay to fall into between two second risers 33 more fast conveniently, then rotate handle portion 11 to the inside, connecting pin 111 slides downwards for shear plate 2, make two second risers 33 press from both sides tight relay simultaneously and extrude the relay shell and produce frictional force, holding handle portion 11 and can easily pull out the relay to the direction pulling of pulling out the relay. When cutting the fuse, the two oppositely arranged cutting plates 2 are controlled to approach and cut the fuse through the blade edges 21 by rotating the handle parts 11.
