[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] like Figure 1-6 As shown, this application provides a handheld clamp for a mask protective film, comprising: The main handle 1 is used for hand gripping and is fixedly connected to the clamping part, driving the clamping part to move horizontally or vertically; Trigger 2 is rotatably connected to main handle 1, with one end driving the clamping part and the other end forming a hand gripping part with main handle 1; The main crossbar 6 is fixedly installed with the main handle 1, and the opening and closing of the clamping part is controlled by the trigger 2. The clamping slide 5 is slidably installed with the main crossbar 6 to form a telescopic structure, which drives the clamping part to open and close.

[0020] Specifically, the main handle 1 and the trigger 2 form a lever structure, which is an asynchronous structure, meaning that one end of the lever structure is open and the other end is closed. This design allows the hand to be released when the hand is in an open state, while the clamping part at the other end is closed. When a reset device, such as a spring, is installed on the trigger 2, the clamping part can be in a closed state under normal conditions, avoiding the need to control the clamping tightness of the clamping part by exerting force by hand. The main crossbar 6 and the clamping slide plate 5 achieve linear movement in the telescopic structure direction, and drive the opening and closing movement of the clamping part, realizing that the trigger 2 drives the clamping slide plate 5, and the clamping slide plate 5 drives the clamping part.

[0021] The technical solution of this utility model effectively solves the problem of simple one-handed control of mask protective film clamps. The opening and closing force can be set in advance to facilitate control of the clamping force. During the clamping process of the mask protective film, the extremely fragile mask protective film is protected, and precise control of the mask protective film with zero contact is achieved.

[0022] Furthermore, such as Figure 2 As shown, the clamping part includes a first clamping arm 3 and a second clamping arm 4, which are respectively fixedly installed on the clamping slide plate 5 and the main crossbar 6. A plurality of positioning contacts 31 are provided on the first clamping arm 3 and the second clamping arm 4 respectively, and the positioning contacts 31 clamp and limit the mask protective film.

[0023] As a preferred embodiment, the first clamping arm 3 and the second clamping arm 4 are fixedly connected to the clamping slide plate 5 and the main crossbar 6, respectively, so that the relative positional relationship is maintained during linear movement. The first clamping arm 3 and the second clamping arm 4 serve as the continuation transmission of the clamping slide plate 5 and the main crossbar 6, respectively. Through the telescopic structure constructed by the clamping slide plate 5 and the main crossbar 6, the first clamping arm 3 and the second clamping arm 4 are driven to move relatively closer and further away. The positioning contacts 31 provided on the first clamping arm 3 and the second clamping arm 4 also move relatively synchronously closer and further away. The clamping and releasing of the mask protective film is realized by the control transmission of the trigger 2 to the positioning contacts 31.

[0024] Furthermore, such as Figure 2 and 6 The first clamping arm 3 and the second clamping arm 4 shown are respectively provided with a first positioning groove 32 and a second positioning groove 42. The first positioning groove 32 and the second positioning groove 42 abut against the clamping slide plate 5 and the main crossbar 6 respectively, and the clamping slide plate 5 and the main crossbar 6 are abutted by the extrusion member, so as to realize the fixed installation of the first clamping arm 3 and the clamping slide plate 5, and the fixed installation of the second clamping arm 4 and the main crossbar 6.

[0025] As a preferred embodiment of the above, the first positioning groove 32 and the second positioning groove 42 ensure the relative positional relationship between the first clamping arm 3 and the clamping slide plate 5, and between the second clamping arm 4 and the main crossbar 6 during the clamping operation. That is, it ensures the fixed installation relationship between the first clamping arm 3 and the clamping slide plate 5, and between the second clamping arm 4 and the main crossbar 6. Similarly, the initial distance between the first clamping arm 3 and the second clamping arm 4 can be adjusted by fixing different positions to adapt to different specifications and models of mask protective films.

[0026] Furthermore, such as Figure 6 As shown, the first clamping arm 3 and the second clamping arm 4 are both provided with a first slide rail 43, and the clamping slide plate 5 and the main crossbar 6 are both provided with a second slide rail 63. The first slide rail 43 and the second slide rail 63 are slidably installed to adjust the relative position of the first clamping arm 3 and the clamping slide plate 5, and the relative position of the second clamping arm 4 and the main crossbar 6, respectively.

[0027] In this embodiment, the first slide rail 43 and the second slide rail 63 are locked together, so that the first clamping arm 3 and the clamping slide plate 5, and the second clamping arm 4 and the main crossbar 6 can only achieve linear movement in the extension and retraction direction, while restricting movement in other directions, thus ensuring the relative positional relationship between the first clamping arm 3 and the second clamping arm 4 when adjusting the position.

[0028] Furthermore, such as Figure 4 As shown, one end of the trigger 2 is provided with a push block 23 and a reset block 24, and one end of the clamping slide 5 is provided with a transmission clamping block 51. Push block 23 and reset block 24 are arranged opposite to each other. Push block 23 pushes the clamping slide 5 away from the main crossbar 6, and reset block 24 resets the clamping slide 5. The transmission clamping block 51 is positioned between the push block 23 and the reset block 24, and transmits the movement of the clamping slide plate 5 in the telescopic direction of the telescopic structure.

[0029] In order to better transmit power through the trigger 2, a push block 23 and a reset block 24 are provided at one end of the trigger 2. When the trigger 2 is pulled, the push block 23 abuts against the transmission clamping block 51, pushes the clamping slide plate 5 away from the main crossbar 6, and drives the first clamping arm 3 away from the second clamping arm 4. When the trigger 2 is released, the reset block 24 abuts against the transmission clamping block 51 and pushes the transmission clamping block 51 into the main crossbar 6, and drives the first clamping arm 3 to approach the second clamping arm 4, so that the resulting telescopic structure is controlled by the trigger 2.

[0030] Furthermore, such as Figure 4 As shown, a spring hole 21 is provided on the inner side of the trigger 2 for installing an elastic device, so that the reset block 24 resets the clamping slide 5.

[0031] As a preferred embodiment of the above, the elastic device, such as a spring, can reset the trigger 2 after it has been in the pinched state, that is, switch the open state of the clamping part to the clamping state.

[0032] Furthermore, such as Figure 3 and 5 As shown, the clamping slide 5 is provided with a sliding groove 52, and the main crossbar 6 includes a positioning rod 62 and a cooperating rod 61; The sliding groove 52 and the mating rod 61 are slidably installed together, forming a telescopic structure in a single sliding direction; The positioning rod 62 abuts against the second positioning groove 42.

[0033] In this embodiment, the sliding groove 52 and the mating rod 61 are slidably installed and locked together to ensure linear movement in only one direction in the extension and retraction direction. It should be noted that, unlike a fixed position, the sliding space here is the clamping distance of the clamping part, and there is no need to fix the relative position.

[0034] Furthermore, the opening and closing direction of the positioning contact 31 is the same as the extension and retraction direction of the telescopic structure formed by the main crossbar 6 and the clamping slide plate 5.

[0035] In this embodiment, ensuring that the positioning contact 31, which is positioned opposite to the telescopic structure, is in the same direction better controls the transmission of the trigger 2's starting force.

[0036] Furthermore, such as Figure 4 As shown, the trigger 2 has a fixing hole 22 in the middle, which is rotatably connected to the main handle 1 to form a lever structure.

[0037] As a preferred embodiment of the above, the fixing hole 22 fixes the trigger 2 to the main handle 1, thus constructing a stable lever structure.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
