Unless otherwise specified, the embodiments in this application can be combined with each other.

[0016] Please see Figure 1 A fixture for riveting hands on a dial includes: a base plate 1, a placement seat 2, a mounting block 3, a connecting arm 4, a movable arm 5, and an adjusting component 6.

[0017] The substrate 1 has a first notch 1A. More specifically, one side of the first notch 1A penetrates the vertical outer wall of the substrate 1. Before riveting the dial, a pointer shaft is installed (the pointer is riveted to the pointer shaft). The pointer shaft is vertical. The first notch 1A is used to engage with the pointer shaft so that the dial can be placed / removed from the fixture in a translational manner.

[0018] The placement seat 2 is fan-shaped, meaning that the placement seat 2 has a second notch 2A. The placement seat 2 is fixedly connected to the substrate 1, and the second notch 2A of the fan-shaped ring is aligned with the first notch 1A of the substrate 1. The function of the second notch 2A is the same as that of the first notch 1A.

[0019] The top surface of the mounting base 2 also has a limiting groove 2B for placing the dial. When the dial is placed into the fixture: the dial is slightly higher than the mounting base 2, the dial is moved horizontally, and the pointer shaft enters through the first notch 1A and the second notch 2A. After the dial and the limiting groove 2B are aligned, the dial moves down to the limiting groove 2B. When the dial leaves the fixture: the dial moves up away from the limiting groove 2B, the dial is moved horizontally, and the pointer shaft leaves through the first notch 1A and the second notch 2A.

[0020] Mounting block 3 is fixedly connected to base plate 1, and the fixed connection position is on the outside of placement seat 2.

[0021] The first end of the connecting arm 4 is connected to the mounting block 3, and the second end is fixedly connected to the first clamping block 4A and extends above the placement base 2. Accordingly, a certain gap is left between the first clamping block 4A and the placement base 2 to accommodate the dial.

[0022] The connection between the connecting arm 4 and the mounting block 3 can be a fixed connection or a hinged connection.

[0023] Please see Figure 1 and Figure 5 In some embodiments, the connection between the connecting arm 4 and the mounting block 3 is selected to be hinged. Accordingly, the mounting block 3 has an inclined surface 3A for the connecting arm 4 to abut against, such that the connecting arm 4 is positioned with a first end higher and a second end lower. The inclined surface 3A is also provided with a magnet 3B for magnetically attracting the mounting block 3.

[0024] The torque exerted by gravity on the connecting arm 4 and the magnetic attraction of the magnet 3B on the connecting arm 4 allow the connecting arm 4 to be held relatively stably against the inclined surface 3A. The force on the connecting arm 4 can be manually overcome, and the connecting arm 4 can be swung and flipped to move the connecting arm 4 away from the position above the placement seat 2, making it convenient for the placement seat 2 to be adjusted, disassembled, cleaned and maintained.

[0025] The first end of the movable arm 5 is movably connected to the connecting arm 4, and the second end is fixedly provided with a second clamping block 5A.

[0026] Please see Figure 3 and Figure 4 The connection between the movable arm 5 and the connecting arm 4 can be a hinge or a sliding connection.

[0027] In some embodiments, the connecting arm 4 includes: a first segment 41 for connection with the mounting block 3, a second segment 42 for fixed connection with the first clamping block 4A, and a connector 43 connecting the first segment 41 and the second segment 42. The movable arm 5 has a first through slot 5B through which the connector 43 passes.

[0028] More specifically, the connector 43 can be a fastener. The second segment 42 fits against the first segment 41 and is then fitted with a fastener to fix the second segment 42 relative to the first segment 41. If the connection between the movable arm 5 and the connecting arm 4 is hinged, the first through-hole 5B of the movable arm 5 is circular. If the connection between the movable arm 5 and the connecting arm 4 is sliding, the first through-hole 5B of the movable arm 5 is waist-shaped, and a limiting block 43A that matches the width of the first through-hole 5B is fitted onto the bolt of the fastener.

[0029] Please see Figure 1The adjusting component 6 is located between the movable arm 5 and the connecting arm 4, so that the first clamping block 4A and the second clamping block 5A can switch between the following two states: clamping the pointer shaft of the dial and releasing the pointer shaft of the dial.

[0030] Please see Figure 3 and Figure 4 In some embodiments, the adjusting member 6 includes: a connecting rod 61, a compression spring 62, and an eccentric wheel 63.

[0031] The first end of the connecting rod 61 is fixedly connected to the movable arm 5. More specifically, the movable arm 5 may have a through hole, the first end of the connecting rod 61 is stepped and has a threaded section, and the threaded section passes through the movable arm 5 and is tightened with a nut.

[0032] The second end of the connecting rod 61 passes through the connecting arm 4, meaning the connecting arm 4 has a second through-hole 4B for the connecting rod 61 to pass through. If the connection between the movable arm 5 and the connecting arm 4 is hinged, then the second through-hole 4B is waist-shaped, providing space for the relative swinging of the connecting rod 61. If the connection between the movable arm 5 and the connecting arm 4 is a sliding connection, then the second through-hole 4B is a circular hole that fits into the connecting rod 61.

[0033] The eccentric wheel 63 is rotatably connected to the second end of the connecting rod 61.

[0034] A compression spring 62 is sleeved on a connecting rod 61, with its two ends abutting against the movable arm 5 and the connecting arm 4, respectively. Under the action of the compression spring 62, the outer wall of the eccentric wheel 63 abuts against the outer wall of the connecting arm 4. Correspondingly, rotating the eccentric wheel 63, in conjunction with the compression spring 62, drives the movable arm 5 to move.

[0035] Please see Figure 3 and Figure 4 Based on the above embodiment of "adjusting component 6 includes: connecting rod 61, compression spring 62, eccentric wheel 63", in some embodiments, the eccentric wheel 63 has a mounting groove 63A, and the second end of the connecting rod 61 is located in the mounting groove 63A.

[0036] In this way, the outer wall of the connecting arm 4 is held abutted by the eccentric wheel 63 at both the position above and below the second through slot 4B, resulting in a more even and stable force distribution.

[0037] Please see Figure 1 and Figure 2 Based on the above embodiment of "the adjusting component 6 includes: a connecting rod 61, a compression spring 62, and an eccentric wheel 63", in some embodiments, the connecting arm 4 is fixedly connected to a connecting block 4C, and the connecting block 4C has a slot.

[0038] More specifically, the fixed connection position of the connecting block 4C in the connecting arm 4 can be the top surface of the connecting arm 4. The connecting block 4C can extend beyond the connecting arm 4, and the bottom surface of the extended part can have a first protrusion. The aforementioned groove is formed between the first protrusion and the outer wall of the connecting arm 4.

[0039] A portion of the edge of the eccentric wheel 63 has a second protrusion 63B that engages with a groove. When the eccentric wheel 63 is manually rotated, the second protrusion 63B enters the groove, stopping the manual rotation. The frictional force balances the effect of the compression spring 62, keeping the eccentric wheel 63, connecting rod 61, and movable arm 5 in their respective positions. Correspondingly, manually rotating the eccentric wheel 63 clamps the pointer shaft with the first clamp 4A and the second clamp 5A, allowing for release and making operation more convenient and effortless.

[0040] Based on the above embodiment where "the adjusting component 6 includes: a connecting rod 61, a compression spring 62, and an eccentric wheel 63", in some embodiments, the movable connection between the movable arm 5 and the connecting arm 4 is selected to be a sliding connection.
