[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] See also Figure 1-3 , the embodiments of the present utility model include:
[0024] A pair of convenient tweezers comprises a first tweezer handle 1, a second tweezer handle 2, a pointed chuck 3, anti-slip serrations 4, engaging teeth 5, and an auxiliary opening and closing component 6.
[0025] The rear ends of the first and second handles are arranged relative to each other and are connected and fixed to form a handle portion. The front portions of the first and second handles gradually open outward, and the front ends of the first and second handles are each connected to a pointed chuck. The inner walls of the two pointed chucks are provided with engaging teeth to facilitate clamping objects and prevent them from loosening. The outer side walls of the first and second handles near the pointed chucks are provided with multiple groups of anti-slip serrations to facilitate the operator's grip and use.
[0026] Further preferably, the first clamp handle and the second clamp handle are connected by welding or rivets, or the two can also be an integral structure.
[0027] Further preferably, the pliers handle and the pointed nose chuck are an integrated structure.
[0028] Further preferably, the anti-slip serrations protrude from the outer side wall of the pliers handle to form a boss structure 41 with the pliers handle to define the forward position of the auxiliary pressing seat.
[0029] The auxiliary opening and closing assembly is movably connected with the handle part and moves forward and backward on the handle part to drive the first handle and the second handle to close or open.
[0030] The auxiliary opening and closing assembly comprises an auxiliary pressing seat 61, a sliding channel 62, a first pressing inclined surface 63, a second pressing inclined surface 64, a limiting groove 65 and a limiting clamping head 66.
[0031] The top surface and the bottom surface of the auxiliary pressing seat are provided with push-pull grooves 611 for facilitating the user to hold or take, the sliding channel is arranged in the auxiliary pressing seat, the handle part is movably connected with the sliding channel, the top surface of the sliding channel is provided with the first pressing inclined surface, the bottom surface of the sliding channel is provided with the second pressing inclined surface, the first pressing inclined surface and the second pressing inclined surface gradually incline inward from the front end close to the beak clamp head to the rear end away from the beak clamp head, so that the first pressing inclined surface is in contact with the outer side wall of the first handle and the second pressing inclined surface is in contact with the outer side wall of the second handle, to assist the clamping and closing of the beak clamp head.
[0032] When the auxiliary pressing seat moves forward on the handle part, the first pressing inclined surface and the second pressing inclined surface advance along the first handle and the second handle, so that the first handle and the second handle are clamped inward under the pressure of the first pressing inclined surface and the second pressing inclined surface, thereby causing the beak clamp head to relatively move inward until closed.
[0033] When the auxiliary pressing seat moves backward on the handle part, the first pressing inclined surface and the second pressing inclined surface retreat along the first handle and the second handle, the pressure on the first handle and the second handle decreases and the first handle and the second handle open outward, thereby causing the beak clamp head to relatively move outward until completely open.
[0034] In use, the position of the auxiliary pressing seat can be adjusted according to the size of the actual clamped object to adjust the clamping and closing angle of the beak clamp head, or the position of the auxiliary pressing seat can be moved or further moved after the object is clamped, so that the beak clamp head is kept in a certain degree of clamping and closing state, facilitating the operation and use of the user.
[0035] Further preferably, a plurality of anti-skid strips are arranged on the pressing inclined surface to prevent the auxiliary pressing seat from excessively freely sliding during use, so that the position of the auxiliary pressing seat on the handle part is fixed, and the beak clamp head is kept in a certain degree of clamping and closing state.
[0036] The limiting groove is arranged at the rear part of the handle part, and the limiting clamping head is elastically arranged in the limiting groove through a spring 661. During use, the limiting clamping head protruding from the handle part can block the auxiliary pressing seat to prevent the auxiliary pressing seat from being detached from the handle part. When it is necessary to remove the auxiliary pressing seat, the auxiliary pressing seat only needs to be pushed and pulled outward, and the guide surface 67 at the rear end of the sliding channel will press down the limiting clamping head, so that the auxiliary pressing seat is separated from the handle part.
[0037] Further preferably, light troughs / racks 68 are provided on both sides of the auxiliary pressing seat, and lighting lamps 69 are provided in the light troughs / racks.
[0038] The advantageous effects of the convenient-to-use tweezers of the utility model are as follows: not only can the opening and closing angles of the tweezers be adjusted, but the tweezers can also be kept in a clamping state, so that the user can use the tweezers for clamping operations more easily and conveniently; the tweezers also have a lighting function, are versatile, and are highly practical, thus meeting different usage requirements.
[0039] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
