A tire tread detection apparatus (100) and tire pressure detector setting apparatus (300) with tire tread detection function are provided. The tire tread detection apparatus (100) includes a body casing (10), a driving unit (20), a measuring member (30), a position member (40), and a sense member (60). The driving unit (20), the measuring member (30), and the positioning member (40) are connected. The driving unit (20) is applied for driving the measuring member (30) to protrude outward from the body casing (10) for measuring the tire tread depth of the tire (200). The sense member (60) generates a measurement signal corresponding to the positioning member (40), such that the measurement signal indicates a tire tread depth value. Therefore, the tire tread depth is efficiently and accurately acquired.

The invention relates to a testing system for verifying the correct installation position of a spring pin 10 in a receiving bore 9 of a component. The receiving bore 9 has a coaxially threaded bore 11 on its insertion side for the spring pin 10, into which a sleeve 12 with an external thread and a coaxial sleeve bore 14 can be screwed to a predetermined position. A guide pin 15 is slidably arranged in the coaxial sleeve bore 14, and its spring pin-side guide pin end face 17 projects from the sleeve 12 and is slidable until it abuts the spring pin end face of the spring pin 10 facing it. The system also includes a radial bore 18 in the wall of the sleeve 12, which does not extend completely through the sleeve. A component with a greater radial extent than the thickness of the sleeve wall 12 is radially slidably arranged in this bore.The radial recess 23 in the radially circumferential wall of the guide pin 15 has a bottom and is in the correct installation position of the spring pin 10 and the spring pin-side guide pin end face 17 is in radial overlap with the radial bore 18 and the component is completely immersed in the radial bore 18 and the radial recess 23, and the radial recess 23 is completely or partially out of overlap with the radial bore 18 and the component is partially radially outwardly protruding from the radial bore 18 when the spring pin 10 is in an incorrect installation position and the spring pin-side guide pin end face 17 is in contact with the spring pin end face of the spring pin 10.

An assembly-free tool for maintenance of an engine in a vehicle is described. The tool comprises a bar extending in an axial direction and having a first portion with a first end and a second portion with a second end and a housing surrounding the first portion of the bar. The bar is axially translatable in relation to the housing. The housing comprises an embedded locking structure for holding the bar in a locking position to stop the movement of the bar in the axial direction. The bar, the housing and the locking structure are retained as one unit such that they are non-detachable from each other.

An example device includes a housing including a top portion, and a lower portion which connect together to house a spring, and a bushing disposed inside the housing with a backside of a bushing rested against the spring, and the backside of the bushing is in contact with a probe tip of a depth measurement gauge disposed in a top portion of the housing.

The application discloses a concrete micro-crack measuring device, and belongs to the technical field of building engineering detection. The device comprises a handle, multi-specification conical needles and an electronic vernier caliper. The conical needles are gradually tapered bodies with scales and are suitable for 0.1mm-10mm cracks. The measuring accuracy of the caliper is 0.01mm. During measurement, the matched conical needle is inserted into the crack until the needle is in close contact with the crack, and then the crack width is measured by the caliper, and the depth can be roughly estimated simultaneously. The concrete micro-crack measuring device has the advantages of simple structure, quick operation, accurate measurement, suitability for on-site concrete structure micro-crack detection and long-term monitoring and high practicability.
