Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The utility model provides a portable printer's FPC installation mechanism, as shown in fig. 1 through 3, including seting up mounting groove 3 on fixing base 2 lateral wall, FPC joint is in mounting groove 3, is connected with the dysmorphism jump ring 6 that is used for fixed FPC on the lateral wall of fixing base 2, dysmorphism jump ring 6 and FPC's outer wall laminating, dysmorphism jump ring 6's both ends respectively with fixing base 2 both sides butt, make dysmorphism jump ring 6 be fixed in on the fixing base 2 to make FPC by the centre gripping fix in mounting groove 3.

The special-shaped clamp spring 6 comprises a rod body 601 which is vertically arranged, a first clamping part 602 and a second clamping part 603 which are perpendicular to the rod body 601 are respectively arranged at two ends of the rod body 601, the rod body 601 is attached to the outer wall of the FPC, the rod body 601 is in a cylindrical shape, the first clamping part 602 and the second clamping part 603 are respectively abutted to two sides of the fixing base 2, and the first clamping part 602 and the second clamping part 603 are elastic and can stretch along the axial direction of the rod body 601.

The first clamping portion 602 and the second clamping portion 603 are arranged in opposite directions, a channel is formed in the fixing base 2, the first clamping portion 602 is abutted to one side, away from the mounting groove 3, of the channel, and the rod body 601 is clamped in the channel and is not easy to fall off.

Both sides of the fixing seat 2 are provided with positioning grooves 4, the first clamping part 602 and the second clamping part 603 are respectively clamped with the positioning grooves 4, the positioning grooves 4 have a limiting effect, and the clamping parts are not easy to fall off from the fixing seat 2 and are more stable.

The first joint portion 602 is the undercut form, and second joint portion 603 is the ring form, and the length of the body of rod 601 is the same with the thickness of fixing base 2, when first joint portion 602 joint in constant head tank 4, need use external force to draw up second joint portion 603, make second joint portion 603 joint in constant head tank 4 of opposite side, improve the stability of dysmorphism jump ring 6 through the resilience force of joint portion, because second joint portion 603 need upwards draw up in can the card income constant head tank 4, consequently set it into the ring form, be difficult for blocking.
