[0026] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0027] like Figure 1-5 As shown, this embodiment includes: a needle unloading plate 102, a base 103, a rack 104, a needle bar 105, a gear 106, a sheet pusher block 107, a bearing cover plate 108 and a bearing 109; wherein,

[0028] Needle unloading plate 102: used to eject multiple TIP heads 101 together under the push of the ejecting block 107.

[0029] Base 103: used to install needle rod 105, gear 106, push piece block 107, bearing cover plate 108 and bearing 109, etc.

[0030] The rack 104 is meshed with a plurality of gears 106 at the same time. Pulling the rack 104 can drive the gears 106 to rotate.

[0031] Needle rod 105: used for installing TIP head 101.

[0032] Gear 106: Driven by the rack 104, the gear 106 will drive the needle bar 105 to rotate together when it rotates.

[0033] The sheet pushing block 107 is manually pushed, and the sheet pushing block 107 can drive the connected needle unloading plate 102 to move together.

[0034] Bearing cover plate 108: used to cover bearing 109, prevent bearing 109 from falling off, and increase measurement accuracy.

[0035] Bearing 109: reduces the friction between the needle rod 105 and the base 103, and at the same time limits the circumference of the needle rod 105 to prevent shaking.

[0036] The specific connection method of this embodiment is:

[0037] A rotatable gear 106 is installed in the base 103, the rack 104 is meshed with the gear 106, the needle rod 105 is connected to the gear 106, the TIP head 101 is installed on the needle rod 105, and the rack 104 moves to drive the gear 106, the needle rod 105 and the TIP head 101 to rotate. A bearing 109 is arranged on the outside of the gear 106, and a bearing cover plate 108 is arranged on the outside of the bearing 109, and the needle rod 105 passes through the bearing cover plate 108.
