The watch strap body is placed inside the drilling placement groove. The moving mechanism is fixed to the top center of the fixing mechanism. The storage box is convenient for storing residual material, and the drilling placement groove is convenient for placing the watch strap body.

[0004] The device in the aforementioned patent can collect waste generated during the drilling process of watch straps, reducing the workload of workers. However, the method of waste falling into the storage box through the through-hole has shortcomings: when multiple pieces of waste fall through the through-hole at the same time, the contact between the waste pieces makes it easy for them to block the through-hole, which requires manual unblocking of the through-hole, making it difficult for users to collect waste quickly. Utility Model Content

[0005] In order to overcome the disadvantage of the devices in the patents mentioned above, which are prone to blocking the through holes, the purpose of this utility model is to provide a watch strap drilling device.

[0006] The technical implementation scheme of this utility model is as follows: a watch strap drilling device includes a base, a rotating column, an electric push rod, a drilling machine, a pressure block, an elastic element, a collecting frame, a scraper, and a guide rod. A rectangular placement groove is opened in the middle of the top of the base. A rotating column is connected to the rear side of the top of the base. An electric push rod is connected to the rotating column. A drilling machine is connected to the push rod of the electric push rod. Pressure blocks are slidably connected to both ends of the drilling machine. An elastic element is connected between the pressure block and the drilling machine. A collecting frame is slidably connected to the left side of the bottom of the base. Guide rods are symmetrically arranged at the front and back of the top of the base. Scrapers are slidably connected to the two guide rods. The bottom end of the scraper abuts against the inner bottom end of the placement groove.

[0007] More preferably, it also includes support legs, with support legs symmetrically arranged on the left and right sides of the bottom end of the base, and the support legs are threadedly connected to the base.

[0008] More preferably, the rotating column is composed of a vertical round rod and a horizontal plate that are rotatably connected. The bottom end of the vertical round rod is fixedly connected to the base, and the front end of the horizontal plate is connected to an electric push rod.

[0009] More preferably, it also includes a stop bar, which is connected to the rotating column. The horizontal plate of the rotating column has an arc-shaped notch, and the upper part of the stop bar is located within the arc-shaped notch.

[0010] More preferably, it also includes a rubber pad, with the outer side of the support leg fitted with a rubber pad.

[0011] More preferably, it also includes a pull plate, with the left end of the collection box connected to the pull plate.

[0012] The beneficial effects of this utility model are: 1. Through the cooperative design of the scraper and the guide rod, the waste generated by drilling can be quickly scraped into the collection frame, avoiding the problem of easy clogging through the through-hole collection method, reducing the frequency of manual cleaning and improving work efficiency.

[0013] 2. The structure adopts the cooperation of elastic elements and pressure blocks. During the drilling process, the pressure blocks automatically tighten the watch strap to prevent it from shifting, ensuring accurate drilling position and improving processing quality. It is especially suitable for stable processing of watch straps of different materials. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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] A watch strap drilling device, such as Figures 1-4 As shown, the device includes a base 1, a rotating column 2, an electric push rod 3, a punch 301, a pressure block 302, an elastic element 303, a collection frame 4, a scraper 5, and a guide rod 501. A rectangular placement slot 101 is formed in the center of the top of the base 1, used to place a watch strap to be punched. The rotating column 2 is connected to the rear of the top of the base 1, and the electric push rod 3 is connected to the rotating column 2. The rotating column 2 is formed by a vertical round rod and a horizontal plate rotatably connected together. The bottom end of the vertical round rod is fixedly connected to the base 1, and the front end of the horizontal plate is connected to the electric push rod 3. When the watch strap needs to be placed in the placement slot 101, the horizontal plate can be rotated, causing the horizontal plate to rotate the electric push rod 3 and the punch 301 to the base 1. At the rear, the watch strap is placed, which helps to accurately place the watch strap in the placement slot 101. The push rod of the electric push rod 3 is connected to the punch 301. The punch 301 can punch multiple holes on the entire watch strap at the same time. The left and right ends of the punch 301 are slidably connected to the pressure block 302. The pressure block 302 and the punch 301 are connected to the elastic element 303. The bottom left of the base 1 is slidably connected to the collection frame 4. The top of the base 1 is symmetrically arranged with guide rods 501. The two guide rods 501 are slidably connected to the scraper 5. The bottom end of the scraper 5 abuts against the inner bottom end of the placement slot 101. By pushing and pulling the front side of the scraper 5, the waste in the placement slot 101 can be swept into the collection frame 4.

[0021] like Figures 1-4As shown, it also includes support legs 102, rubber pads 103, stop bars 201, and pull plates 401. Support legs 102 are symmetrically arranged on the left and right sides of the bottom end of the base 1. The support legs 102 are threadedly connected to the base 1. When the device is located on an uneven working surface, the support legs 102 can be rotated to change the contact area between the support legs 102 and the base 1, thereby ensuring that all parts of the top of the base 1 are on the same horizontal plane. Rubber pads 103 are sleeved on the outer side of the support legs 102. The rubber pads 103 increase the friction between the device and the working surface, preventing the device from sliding during drilling. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) A stop bar 201 is connected to the rotating column 2. An arc-shaped notch 202 is opened on the horizontal plate of the rotating column 2. The upper part of the stop bar 201 is located in the arc-shaped notch 202. Through the cooperation of the stop bar 201 and the arc-shaped notch 202, the rotation angle of the horizontal plate can be effectively controlled, so as to quickly rotate the horizontal plate to the top of the placement slot 101. A pull plate 401 is connected to the left end of the collection frame 4. The pull plate 401 makes it easy for the user to pull the collection frame 4 to clean up the waste. When it is necessary to clean up the waste in the collection frame 4, pull the collection frame 4 out from the left side of the base 1 and then pour out the waste in the collection frame 4.

[0022] When using this device to drill holes in a watch strap, first rotate the rotating column 2 so that the horizontal plate rotates backward around the vertical rod as the center of rotation. The drilling machine 301 rotates with the horizontal plate, and the stop bar 201 separates from the arc-shaped notch 202 (the state diagram of this device can be referred to at this time). Figure 4 Place the watch strap into the placement slot 101, rotate the horizontal plate so that the punch 301 returns to directly above the watch strap, at which point the stop lever 201 abuts against the left inner wall of the arc-shaped notch 202 (see reference). Figure 1 The pull plate 401 is pushed, causing the collection frame 4 to move to the left. This activates the electric push rod 3, which moves the punch 301 downwards. When the bottom of the pressure block 302 contacts the watch strap, the upper part of the pressure block 302 moves upwards. During this process, the elastic element 303 (a spring) changes from its initial state to a compressed state. When the bottom of the punch 301 is tightly against the watch strap, the upper part of the pressure block 302 stops moving upwards. At this point, under the action of the elastic element 303, the pressure block 302 presses down on the watch strap, preventing it from... During the drilling process, displacement occurs, and the drilling machine 301 is started. The drilling machine 301 drills holes in the entire watch strap in one go. After the drilling is completed, the electric push rod 3 drives the drilling machine 301 to move upward. During this process, the elastic element 303 resets, and the pressure block 302 returns to the initial position, removing the watch strap from the placement groove 101. The scraper 5 is moved to the left, so that the waste material in the placement groove 101 (i.e., the waste material generated by drilling) is scraped into the collection frame 4. The scraper 5 is moved to the initial position on the right, and the above operation is repeated to drill holes in the next watch strap.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
