[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 2-7 As shown, one embodiment of this utility model provides a watch case opener, including a case opener body 1, a sliding part 2, a screw linear drive mechanism, and two clamping blades 5; the case opener body 1 includes a fixing part 101, a connecting part 102, and a gripping part 104 connected in sequence; the sliding part 2 is slidably mounted on the connecting part 102 along the length direction of the case opener body 1; two clamping blades 5 are detachably mounted on the same side of the sliding part 2 and the fixing part 101; the side of the case opener body 1 is provided with a scale 106; the screw linear drive mechanism is mounted on the case opener body 1 to drive the sliding part 2 away from or towards the fixing part 101.

[0021] In this embodiment, since the clamping blade 5 is detachably mounted on the sliding part 2 and the fixing part 101, the corresponding clamping blade 5 can be replaced according to different bayonet shapes, thus enhancing its practicality. In actual use, maintenance personnel can select matching blades (up to 7 types) according to the shape of the watch case back bayonet to avoid problems such as slippage, damage to the watch case back, or inability to apply force due to mismatched blades.

[0022] In addition, the previous fixing claw 11 was an independent component, which was fixed to the cover opener plate 10 by the cooperation of the fixing nut 13 and the fixing claw threaded rod 111. This was more troublesome to assemble each time, and once the threads on the fixing nut 13 or the fixing claw threaded rod 111 wore out, the fixing claw 11 may become loose.

[0023] In contrast, in this embodiment, the fixing part 101 is integrally formed with the cover opener body 1, so the fixing part 101 cannot be assembled, making it more convenient to use. Secondly, there is no loosening problem.

[0024] In this embodiment, as Figure 2 and Figure 5 As shown, the bottom of the fixing part 101 is provided with a vertically arranged first insertion hole, and the side of the fixing part 101 away from the connecting part 102 is provided with a first set screw hole. The axis of the first set screw hole is perpendicular to the axis of the first insertion hole, and the first set screw hole and the first insertion hole are connected. A first locking set screw 8 is provided in the first set screw hole.

[0025] A vertically arranged second insertion hole is provided at the bottom of the sliding part 2, and a second set screw hole is provided on the side of the sliding part 2. The axis of the second insertion hole is perpendicular to the axis of the second set screw hole, and the second insertion hole and the second set screw hole are connected. A second locking set screw 9 is provided in the second set screw hole.

[0026] In addition, the top of the clamping head 5 has a plug-in part that can be inserted into the first socket and the second socket.

[0027] Thus, when assembling the clamping head 5 onto the fixing part 101, simply insert the insertion part of the clamping head 5 into the first insertion hole at the bottom of the fixing part 101, and then tighten the first locking screw 8 to lock the clamping head 5. Subsequently, simply loosen the first locking screw 8 to remove the clamping head 5. The process of assembling the clamping head 5 onto the sliding part 2 is the same, and will not be described in detail here to avoid redundancy.

[0028] It should be noted that the two locking screws in this embodiment can also be replaced with bolts, screws, etc., as long as they can hold the insertion part of the clamping head 5.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, the connecting part 102 is provided with a strip hole 103, which extends along the length of the connecting part 102. The strip hole 103 is located in the middle of the connecting part 102 to divide the connecting part 102 into two connecting rods. The sliding part 2 is slidably installed on the strip hole 103, that is, the sliding part 2 is slidably installed between the two connecting rods.

[0030] like Figure 3 As shown, the sliding part 2 is I-shaped, and each of its front and rear sides is provided with a slot 201 that is adapted to the connecting rod. In this way, the two slots 201 of the sliding part 2 can be engaged with the two connecting rods of the connecting part 102 to improve the stability of the sliding part 2 when it moves.

[0031] In some embodiments, such as Figure 4 and Figure 5 As shown, the linear drive mechanism includes a screw 3 and a rotating threaded seat 4. A mounting hole is provided on the gripping part 104 along its axial direction, and the rotating threaded seat 4 is rotatably installed in the strip-shaped hole 103. One end of the screw 3 is inserted into the mounting hole of the gripping part 104, and the other end passes through the rotating threaded seat 4 and is detachably connected to the sliding part 2. The rotating threaded seat 4 and the screw 3 are threadedly connected.

[0032] Thus, when adjusting the distance between the sliding part 2 and the fixed part 101, simply rotate the threaded seat 4. Rotating the threaded seat 4 drives the screw 3 to move the sliding part 2 closer to or away from the fixed part 101, thereby adjusting the distance between the two clamping heads 5.

[0033] In some embodiments, such as Figure 5 and Figure 7 As shown, from the fixed part 101 to the gripping part 104, the moving part is provided with a countersunk bolt hole 202 and a round hole 203 connected in sequence. The countersunk bolt hole 202 and the round hole 203 are coaxially arranged. The end of the screw 3 near the sliding part 2 is provided with a threaded hole that is compatible with the countersunk bolt 7.

[0034] When assembling the screw 3 and the sliding part 2, simply insert the end of the screw 3 into the round hole 203 of the sliding part 2, and finally insert the countersunk bolt 7 into the countersunk bolt hole 202 so that the end of the countersunk bolt 7 contacts the threaded hole at the end of the screw 3. Then, tighten the countersunk bolt 7 until it cannot be tightened any further. In this way, the screw 3 and the sliding part 2 can be quickly assembled, and installation and disassembly are very convenient. It is also convenient to replace the sliding part 2 or the screw 3 at any time.

[0035] It should be noted that traditional rotary handle lid openers rely on manual adjustment of the distance between the moving claw 12 and the fixed claw 11 by pushing the moving claw 12 by feel, requiring multiple adjustments. However, in this embodiment, as... Figure 2 As shown, a scale 106 is provided on the front of the cover opener. Thus, when the sliding part 2 is driven to move closer to or away from the fixed part 101 by rotating the threaded seat 4, the distance between the two clamping blades 5 can be accurately observed through the scale 106. In addition, the diameter of the bottom cover (i.e., the diameter of the annular jaw) can be measured in advance using a ruler, and then the distance between the two clamping blades 5 can be quickly adjusted according to the measurement result and the scale 106.

[0036] In this embodiment, as Figure 3 and Figure 4 As shown, the rotating threaded seat 4 is a cylinder, and grooves matching the rotating threaded seat 4 are respectively provided on the inner walls of both sides of the strip hole 103. That is to say, grooves are respectively provided on the inner walls of the two connecting rods before and after the connecting part 102. The rotating threaded seat 4 is embedded between the two grooves, and the axial direction of the rotating threaded seat 4 is consistent with the axial direction of the screw 3. The grooves restrict the movement of the rotating threaded seat 4 along the axial direction of the screw 3, so as to drive the screw 3 to move more stably.

[0037] In some embodiments, an anti-slip structure is provided on the side of the rotating threaded seat 4. The anti-slip structure can be a common anti-slip method such as an anti-slip sleeve or anti-slip texture. This increases the friction between the hand and the surface of the rotating threaded seat 4, making it more labor-saving.

[0038] In some embodiments, the grip portion 104 is cylindrical, and a cylindrical grip portion 104 is more convenient for a person to hold. Of course, a multi-faceted or other shaped grip portion 104 is also within the protection scope of this utility model.

[0039] In some embodiments, the grip portion 104 has anti-slip texture 105 on its peripheral surface to facilitate gripping.

[0040] In some embodiments, such as Figure 5 As shown, a mounting hole is provided on the gripping part 104 along its axial direction, which passes through the gripping part 104. The mounting hole includes a circular hole and a cylindrical hole 107 connected in sequence. The circular hole and the cylindrical hole 107 are coaxially arranged. The diameter of the cylindrical hole 107 is larger than the diameter of the circular hole. The circular hole is close to the sliding part 2, while the cylindrical hole 107 is far away from the sliding part 2. The circular hole is adapted to the screw 3.

[0041] Thus, when installing the screw 3, the screw 3 can be inserted from the opening at the end of the holding part 104 away from the fixing part 101. The screw 3 passes through the cylindrical hole 107 and the round hole in sequence and is then threadedly connected to the rotating threaded seat 4.

[0042] It should be noted that, since the diameter of the round hole on the gripping part 104 matches that of the screw 3, external impurities are prevented from entering the interior of the gripping part 104.

[0043] In addition, a sealing cap 6 is installed at the opening of the cylindrical hole 107 to prevent external impurities from entering the gripping part 104 and interfering with the rotation of the screw 3.

[0044] In this embodiment, the minimum stroke of the sliding part 2 is 10mm and the maximum stroke is 48mm.

[0045] In summary, this watch case opener has at least the following advantages: First, traditional watch case openers have a blade head and claw body that are integrally molded, making them only compatible with specific types of latches. In this design, however, the clamping blade head 5 is secured by a set screw, allowing for quick replacement. In practical use, repair personnel can select a matching blade head (up to 7 types) based on the shape of the watch case back latch (such as dotted, striped, or irregular shapes), avoiding slippage, damage to the watch case, or inability to apply force due to mismatched blade heads. This design is particularly suitable for repairing watches of various brands and models.

[0046] Secondly, the fixing claw 11 of the traditional cover opener needs to be fixed separately by the fixing nut 13. After long-term use, the threads are prone to wear and loosening. However, the fixing part 101 is integrally formed with the cover opener body 1, which has a stable structure and does not require assembly. It eliminates the risk of loosening and saves assembly steps. It is direct and reliable when used and is more suitable for maintenance environments with frequent operation.

[0047] Third, the sliding part 2 cooperates with the two connecting rods of the connecting part 102 through the two side slots 201. When moving, the sliding part 2 is not easy to shake or deflect. In actual operation, this structure can keep the two blades aligned at all times, avoid the problem of blade misalignment and misalignment of the slots caused by the shaking of the sliding part 2, and improve the success rate of opening the cover.

[0048] Fourth, traditional case openers rely on touch to move the moving claw 12, requiring repeated attempts to align it with the slot. This design drives the screw 3 by rotating the threaded seat 4, which can finely adjust the distance between the two cutting heads. With the scale 106 on the front, maintenance personnel can first measure the diameter of the case and then quickly adjust it to the appropriate distance according to the scale 106, reducing the time spent on repeated adjustments.

[0049] Fifth, the screw 3 is connected to the sliding part 2 by the countersunk bolt 7, which makes disassembly convenient.

[0050] Sixth, the grip part 104 has an anti-slip design, making operation easier. The cylindrical grip part 104 is equipped with anti-slip texture 105, which conforms to ergonomics and makes the grip more stable. In addition, the rotating threaded seat 4 is also equipped with anti-slip texture, which makes it less prone to slipping and provides better conditions for applying force.
