[0013] As a further improvement of this utility model, the grip includes a pressing part and a grip seat; the pressing part is fixedly disposed on the upper side of the grip seat, the pressing part is a hollow sphere, and the grip seat has a thread on the inner side.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By incorporating a handle, hammer, force transmission needle, marking needle, and outer shell, the marking needle contacts the metal nameplate. Under external force, the marking needle pushes up the hammer through the force transmission needle. The impact spring releases its elasticity, causing the hammer to generate impact force. Repeated operation can achieve continuous marking of the metal nameplate. This allows operators to perform simple marking processes in limited working environments. At the same time, the marking device is small in size, easy to carry, and has low production costs. Attached Figure Description

[0022] Specific Implementation Example 1: Please refer to Figures 1-4 A manual marking device, comprising, from top to bottom, a handle 1, a hammer 2, a force transmission needle 3, and a marking needle 4.

[0023] A housing 5 is provided on the lower side of the grip 1 to cover and support the hammer 2, the force transmission needle 3, and the pressure needle 4. The grip 1 includes a pressing part 11 and a grip base 12. The pressing part 11 is fixedly disposed on the upper side of the grip base 12. The pressing part 11 is hollow and spherical. The grip base 12 has threads on its inner side.

[0024] The upper end of the hammer 2 is connected to the inside of the handle by an impact spring 21, and the lower end of the hammer 2 is provided with an impact groove 22.

[0025] The upper end of the force-transmitting needle 3 is provided with a force-transmitting shaft 31 and a force-transmitting boss 33 that can be inserted into the impact groove 22. The force-transmitting shaft 31 is eccentrically positioned with respect to the impact groove 22, and a force-transmitting spring 32 is provided on the outer side of the force-transmitting shaft 31. Furthermore, the size of the force-transmitting shaft 31 and the impact groove 22 are matched, and the depth of the impact groove 22 is less than the length of the force-transmitting shaft 31. The force-transmitting boss 33 is located at the bottom of the force-transmitting needle 3, and there is a gap between the outer side of the force-transmitting boss 33 and the inner sidewall of the housing 5. The lower end of the force-transmitting spring 32 is fixedly connected to the upper side of the force-transmitting boss 33.

[0026] The upper end of the pressure needle 4 abuts against the lower end of the force transmission needle 3. When the pressure needle 4 is pushed upward by an external force, the force transmission spring 32 and the impact spring 21 are compressed. When the force transmission spring 32 is compressed to a certain extent, the position of the force transmission shaft 31 is corrected, so that the force transmission shaft 31 is inserted into the impact groove 22.

[0027] The housing 5 includes an upper housing 51 and a lower housing 52. The upper housing 51 has, from top to bottom, a first through hole 512, a transition hole 513, a tapered hole 514, and a second through hole 515, all coaxially aligned with the hammer 2. The bottom of the first through hole 512 abuts against the lower end of the hammer 2 to support it. The diameter of the transition hole 513 is the same as the upper diameter of the tapered hole 514. The upper diameter of the tapered hole 514 is smaller than its lower diameter, and its upper diameter is larger than the diameter of the force transmission shaft 31. The upper part of the force transmission spring 32 abuts against the top of the second through hole 515 to limit its compression.

[0028] The lower housing 52 has a third through hole 522 and a pinhole 523 sequentially formed from top to bottom inside. The diameter of the third through hole 522 is larger than the diameter of the pinhole 523 but smaller than the diameter of the second through hole 515. The force transmission needle 3 is slidably connected to the third through hole 522. The pressure mark needle 4 is slidably connected to the pinhole 523.

[0029] The upper housing 51 has a first threaded portion 511 at its upper end, and the handle 1 has an internal thread at its lower end, and the upper housing 51 and the handle 1 are threaded together. The lower housing 52 has a second threaded portion 521 at its upper end, and the upper housing 51 has an internal thread at its lower end, and the upper housing 51 and the lower housing 52 are threaded together.

[0030] Working principle:

[0031] Align the lower end of the marking needle 4 with the metal nameplate to be marked. The operator holds the handle 1 and applies a downward force to the marking device. The marking needle 4 contacts the metal nameplate and moves upward. The marking needle 4 drives the force transmission needle 3 to move upward, pushing the impact spring 21 between the hammer 2 and the handle 1 to compress. The force transmission spring 32 abuts against the lower side of the tapered hole 514 and is compressed. When the force transmission spring 32 is compressed to a certain extent, the force transmission needle 3 tilts at a certain angle, correcting the eccentric force transmission shaft 31 and inserting it into the impact groove 22. At the same time, the impact spring 21 releases its elasticity, causing the hammer 2 to fall, which in turn causes the force transmission needle 3 and the marking needle 4 to generate an impact force downward, completing one marking of the metal nameplate. Repeatedly mark the metal nameplate continuously to complete the marking.
