The utility model discloses a sleeve repair tool for a fuel manifold of a turboshaft engine, which comprises a support with the top end provided with a penetrating column with threads on the inner wall, and further comprises a threaded pressing rod with the top end provided with a pulling rod, and the threaded pressing rod is in threaded connection with the penetrating column through the threads on the outer wall; a semi-arc-shaped pressing plate is arranged at the bottom of the T-shaped sliding block, and the T-shaped sliding block is movably connected with the threaded pressing rod; a shape correcting arc plate is arranged on the positioning column opposite to the semi-arc pressing plate, and the positioning column is located at the middle section of the support; and the gland is connected to the positioning column through a bolt. According to the sleeve repairing tool for the turboshaft engine fuel main pipe, the problems that in the prior art, manual positioning is not accurate, and pipe wall cracks and internal threads are prone to being crushed to be scrapped due to repeated knocking are solved.

The utility model discloses a dynamic image projection lamp which comprises a lamp shell assembly and a lamp source assembly. The lamp shell assembly comprises a lamp body and a front cover, a first light outlet hole is formed in the front cover, and a lamp source assembly is arranged in a cavity between the front cover and the lamp body. The lamp source assembly is sequentially provided with a light source assembly and a pattern assembly in the light emitting direction of a light source. The light source assembly comprises a lamp panel and two or more lamp beads arranged on the lamp panel. The pattern assembly comprises a pattern disc and a plurality of pattern pieces, first light through holes in one-to-one correspondence with the lamp beads are formed in the pattern disc, the pattern pieces are arranged on the first light through holes in a one-to-one correspondence mode, and the multiple pattern pieces can project a dynamic pattern effect in sequence; and the control module is electrically connected with the light source assembly, and the control module is used for controlling the lamp beads to be circularly lightened one by one according to the pattern sequence of the pattern pieces. The projection lamp is simple in structure and low in cost, can output dynamic images to a preset scene, and improves the display effect and interaction interestingness of the projection lamp.

The utility model relates to a manual focusing mechanism for double optical paths, and belongs to the technical field of focusing of handheld equipment. Comprising a focusing frame, a first focusing mechanism and a second focusing mechanism. The focusing frame comprises a focusing fixing seat, a middle adapter plate and a focusing upper cover, the first focusing mechanism comprises a first focusing wheel, a first focusing lead screw, a first focusing nut, a focusing pull rod and a first connecting arm, and the second focusing mechanism comprises a second focusing wheel, a transmission shaft, a second focusing lead screw, a second focusing nut and a second connecting arm. The focusing mechanism can be independently assembled, then the focusing mechanism and the lens cone assembly are assembled, the focusing mechanism is convenient to disassemble, assemble and maintain, batch production can be carried out, the first focusing mechanism and the second focusing mechanism which are assembled achieve the independent manual focusing function of the double-optical-path lens, the relative position between the two lenses in the focusing process is stable, and the focusing effect is good. And the optical path of the other lens cone assembly is not interfered, so that the focusing clearness of each lens cone assembly is ensured, and the overall performance of the handheld equipment is improved.

This invention provides an eyepiece with a 360° rotatable and positionable eyecup, comprising an eyepiece tube, a tube support at one end of the eyepiece tube, and an eyecup that can rotate circumferentially relative to the eyepiece tube, coaxially mounted at the other end of the eyepiece tube via an eyecup adjustment assembly. A focusing assembly is located on the outer side of the eyepiece tube between the tube support and the eyecup. This invention fixes the eyecup to the eyepiece tube by designing an eyecup focusing assembly, allowing the eyecup to move with the eyepiece tube during focusing, thus avoiding the risk of the eyepiece touching the eyeball. Simultaneously, the eyecup can be independently rotated to any angle through adjustment of the eyecup focusing assembly. Furthermore, the entire eyepiece structure achieves the required focusing and eyecup angle adjustment functions, requires fewer parts, is easy to install, and has high assembly and production efficiency.

This invention relates to a slope reinforcement device for geotechnical engineering, comprising a carrier, a mesh laying mechanism, a reinforcement mechanism, and a seeding mechanism. The carrier includes an installation section and a moving section, with the moving section located within the installation section. Along its moving direction, the installation section has mesh laying positions, anchor bolt positions, and seeding positions, with each anchor bolt position having a drilling point. The mesh laying mechanism includes a placement cylinder installed within the installation section and located at the mesh laying position. The reinforcement mechanism includes a turntable, a drilling section, a measuring section, a feeding section, and a grouting machine. The turntable is installed within the installation section and located at the anchor bolt position. The drilling section, measuring section, feeding section, and grouting machine are respectively located on the turntable and spaced apart circumferentially. The seeding mechanism is installed within the installation section and located at the seeding position. This solution ensures consistent drilling depth and improves the stability of the slope and vegetation net; it combines physical and natural slope stabilization, improving the slope stabilization effect and replacing manual mesh laying and concrete pouring, reducing the workload of workers and improving work efficiency.
